A major cyber outage caused by a faulty update from cybersecurity firm CrowdStrike has led to widespread disruptions across multiple industries worldwide.
The glitch, which affected Windows-based systems, resulted in grounded flights, healthcare appointment cancellations, and banking service interruptions.
Major airlines including Delta, American, United, and Allegiant reported significant operational impacts. As of 12:42 p.m. ET Friday, over 30,000 flights were delayed globally, with 5,944 delays affecting flights within, into, or out of the United States, according to flightaware.com.

In Phoenix, Arizona, emergency response systems were down, forcing some police and ambulance providers to dispatch vehicles manually.
Banking and financial services firms in Australia, India, and Germany warned customers of service disruptions. Media organizations were also affected, with Britain’s Sky News temporarily unable to broadcast live.
CrowdStrike CEO George Kurtz announced on social media that the issue had been identified and a fix deployed. The company clarified that the problem was not a security incident or cyberattack and only affected Windows systems.
The White House confirmed that President Joe Biden had been briefed on the situation, with his administration communicating with CrowdStrike and impacted entities.
Amazon Web Services warned customers of potential “connectivity issues and reboots” related to the CrowdStrike outage. Shipping giants FedEx and UPS reported disruptions, warning of possible package delays.
Transportation Secretary Pete Buttigieg told CNBC that transportation delays should be “resembling normal” by Saturday, although ripple effects may continue throughout Friday.
